RESUMO
Background and aimsPrevalence of diabetes is a vital factor in COVID-19s clinical prognosis. This study aimed to investigate and compare the efficacy of High-flow Nasal Cannula (HFNC) with/without non-rebreather mask (NRM) use on critical COVID-19 patients with/without diabetes. MethodsFor analysis and comparison, epidemiological, biochemical, and clinical data were collected from 240 HFNC ({+/-}NRM) treated severe and critical COVID-19 patients (diabetic = 136; non-diabetic = 104) admitted into ICUs of five hospitals in Chattogram, Bangladesh. Results59.1% of patients with fever had diabetes (p=0.012). ICU stay was longer for diabetic patients (9.06{+/-}5.70) than non-diabetic patients (7.41{+/-}5.11) (p=0.020). Majority of the hypertensive patients were diabetic (68.3%; p<0.001). Majority of diabetic patients (70.4%; p<0.005) had elevated creatinine levels. Partial pressure of oxygen (mmHg) after HFNC (only) administration was significantly (p=0.031) higher in non-diabetic patients (69.30{+/-}23.56) than in diabetic patients (61.50{+/-}14.49). Diabetic (62.64{+/-}13.05) and non-diabetic patients (59.40{+/-}13.22) had almost similar partial pressure of oxygen (mmHg) from HFNC with NRM. Patients with elevated RBS required NRM with HFNC five times (AOR=5.1, 1.2-20.8) higher than others. Besides age, and hypertension were significantly associated with the HFNC+NRM treated diabetic patients. Factors those affected the HFNC only treated patients were fever and impaired glucose tolerance. ConclusionsThe results of this study imply that oxygen supply with HFNC and NRM may be beneficial for the elderly/hypertensive diabetic patients with COVID-19 associated AHRF; and that increased blood glucose level could be a determinant for the need of HFNC + NRM treatment. HighlightsO_LIElderly diabetic patients required both HFNC and NRM to increase oxygen saturation. C_LIO_LIHypertension may be a factor for diabetic patients with COVID-19 requiring HFNC and NRM together. C_LIO_LI HFNC + NRM-combination therapy might be needed when blood glucose levels rise. C_LI
RESUMO
ObjectivesThis study aimed to analyse the epidemiological and clinical characteristics of critical COVID-19 cases and investigate risk factors including comorbidities and age in relation with the clinical aftermath of COVID-19 in critical cases in Bangladesh. MethodsIn this retrospective study, epidemiological and clinical characteristics, complications, laboratory results, and clinical management of the patients were studied from data obtained from 168 individuals diagnosed with an advanced prognosis of COVID-19 admitted in two hospitals in Bangladesh. ResultsIndividuals in the study sample contracted COVID-19 through community transmission. 56.5% (n = 95) cases died in intensive care units (ICU) during the study period. The median age was 56 years and 79.2% (n=134) were male. Typical clinical manifestation included Acute respiratory distress syndrome (ARDS) related complications (79.2%), fever (54.2%) and cough (25.6%) while diabetes mellitus (52.4%), hypertension (41.1%) and heart diseases (16.7%) were the conventional comorbidities. Clinical outcomes were detrimental due to comorbidities rather than age and comorbid individuals over 50 were at more risk. In the sample, oxygen saturation was low (< 95% SpO2) in 135 patients (80.4%) and 158 (93.4%) patients received supplemental oxygen. Identical biochemical parameters were found in both deceased and surviving cases. Administration of antiviral drug Remdesivir and the glucocorticoid, Dexamethasone increased the proportion of surviving patients slightly. ConclusionsSusceptibility to developing critical illness due to COVID-19 was found more in comorbid males. These atypical patients require more clinical attention from the prospect of controlling mortality rate in Bangladesh.
